Review of the Williams - Bartlett - Kshirsagar Work on Direction and Collinearity Factors in Discriminant Analysis

摘要

In discriminant analysis, the problem of examining the dimensionality of the configuration of the means of various graphs and of testing the adequacy of the directions and number of assigned discriminant functions are of some importance. A great deal of work is done in this and related areas (principal components and assignment of scores to categories) as done by Williams, Bartlett, Kshirsagar, and others. The whole area is reviewed in the paper. (Author)
